In 1883, the volcano on the Indonesian island of Krakatoa erupted with 13,000 times the power of an atomic bomb. The sound of the spewing smoke and rock was reportedly heard thousands of miles away, as far as islands off the eastern coast of Africa. Hundreds in a nearby Sumatran town died almost instantly when flaming ash incinerated their homes, and many more were washed away by subsequent megatsunamis. An estimated 36,000 or so perished in total. Krakatoa itself then slumped into the boiling depths of the ocean, but a new island at the site was spotted in 1927, and it still occasionally spits lava into the sky. It's been dubbed Anak Krakatoa, or Child of Krakatoa.
